CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation application of prior application Ser. No. 16/269,981, filed on Feb. 7, 2019, which is based on and claims priority under 35 U.S.C. § 119(a) of a Korean patent application number 10-2018-0016140, filed on Feb. 9, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND 1. Field

The disclosure relates to a display. More particularly, the disclosure relates to a display including a bending region.

2. Description of Related Art

An electronic device may refer to a device that performs specific functions in accordance with programs installed therein, such as an electronic notepad, a mobile multimedia player, a mobile communication terminal, a tablet personal computer (PC), a video/sound device, a desktop/laptop computer, and an automobile navigation system, including home appliances. For example, electronic devices can output information stored therein using sound or images. As electronic devices have become highly integrated and high-speed and large-capacity wireless communication has become popular, recently it has become possible to integrate various functions into a single electronic device.

Portable electronic devices include a window and users can see images displayed on the display in the electronic devices through the window from the outside. The window may include a transparent area and a bezel area (e.g., a dead space) surrounding the transparent area. The bezel area is opaque, so it can hide wiring and components under the bezel area.

Portable electronic devices may be formed such that the transparent area of a window is large and the bezel area (e.g., dead space) is small so as to achieve a large screen. The bezel area, which is an area for arranging wiring connected to electrodes of a display or a touch panel in the electronic device, can hide the wiring and provide a gap that can mitigate electromagnetic interference among the wires. For example, the larger the bezel area, the larger the gaps between the wiring may be, that is, electromagnetic interference can be mitigated, or signals can be stably transmitted by sufficiently securing line width of the wirings. However, as the bezel area is increased, the area in which images can be output may be reduced.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

SUMMARY

Wiring connected to a display or a touch panel may be arranged substantially on a substrate (e.g., a flexible printed circuit board) and may be connected to a driving circuit (e.g., a display driver integrated circuit (IC) (display driver integration (DDI))) or a touch sensor driver IC (T-IC) for driving the display or the touch panel. This substrate may be disposed substantially to correspond to a bezel area and may be bent in a curved line shape or a curved surface shape to increase the ratio of the screen area or reduce the bezel area.

As the substrate is bent, the driving circuit can be disposed under the display, so the bezel area can be decreased. According to the substrate, the bending portion of the substrate formed in a curved line shape or a curved surface shape may be damaged by external force, so a crack may be generated in the wiring. Cracks may even be generated in the wiring by direct contact or friction between a window and the bending portion.

Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide a display in which a first wiring and a second wiring can be doubly configured in a bending region of a substrate.

Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

In accordance with an aspect of the disclosure, a display is provided. The display includes a pixel layer including a plurality of pixels, a substrate disposed under the pixel layer and including a first area on which the pixel layer is disposed, and a second area extending out of the pixel layer from the first area, at least a partial area of the second area being bendable, wherein the substrate includes: a wiring layer including at least one first wiring electrically connected with at least one pixel of the plurality of pixels, and disposed from the first area to the second area, and at least one second wiring disposed in the at least partial area and electrically connected with the at least one first wiring in the second area.

In accordance with another aspect of the disclosure, a display is provided. The display includes a display panel including a first area (e.g., an active area (AA)) including a plurality of pixels, and a second area including a bendable bending region, at least one first wiring electrically connected with at least one pixel of the plurality of pixels, and disposed on the first area and the bending region of the second area, and at least one second wiring electrically connected with the at least one first wiring in the second area, and disposed on the bending region of the second area.

In accordance with another aspect of the disclosure, a display is provided. The display includes a pixel layer including a plurality of pixel, and a substrate disposed under the pixel layer, including a first area in which the pixel layer is disposed, and a second area extending out of the pixel layer from the first area, and at least a partial area of the second area being bendable, wherein the substrate includes: at least one first wiring electrically connected with first pixels of the plurality of pixels, and disposed from the first area to the second area, and at least one second wiring electrically connected with second pixels different from first pixels electrically connected with the first wiring, and disposed from the first area to the second area.

In accordance with another aspect of the disclosure, a display is provided. The display includes a substrate including a first area and a second area extending from the first area, at least a partial area of the second area being bendable, at least one first wiring disposed from the first area to the second area, at least one second wiring disposed in the at least a partial area of the second area, and electrically connected with the at least one first wiring in the second area, and at least one wiring layer disposed between the at least one first wiring, and the at least one second wiring and separating the at least one first wiring and the at least one second wiring.

In accordance with another aspect of the disclosure, a display is provided. The display includes a substrate including a first area, a second area extending from a first side of the first area, and a third area extending from a second side of the first area, at least a partial area of the second area being bendable, and at least a partial area of the third area being bendable, at least one first wiring disposed from the first side of the first area to the second area, at least one second wiring disposed in the at least a partial area of the second area, and electrically connected with the at least one first wiring in the second area, at least one third wiring disposed from the second side of the first area to the third area, and at least one fourth wiring disposed in the at least a partial area of the third area, and electrically connected with the at least third wiring in the third area.

According to various embodiments, since a first wiring and a second wiring are doubly separated in a bending region of a substrate, it is possible to mitigate interference between a window of an electronic device and the bending region. Further, two wirings that are arranged in parallel in the related art can be disposed to substantially overlap each other on different layers in various embodiments, so the width of the bending region can be reduced.

According to various embodiments, since a first wiring and a second wiring are doubly disposed in a bending region of a substrate, the same wiring can be doubly achieved. Accordingly, even if a crack is generated in at least one of the first wiring and the second wiring, the other wiring can be electrically connected with the display driver integration of an electronic device, so a poor wiring rate of a product can be reduced.

Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the disclosure.

The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the AP) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).
